启动命令 mongo 时出现警告

我的服务器在 Ubuntu 16.04、Nginx 上运行。

mongo当我在服务器上输入命令时出现以下警告:

Server has startup warnings:

2016-07-31T16:59:14.391+0200 I CONTROL  [initandlisten] ** WARNING: Cannot detect if NUMA interleaving is enabled. Failed to probe "/sys/devices/system/node/node1": Permission denied

你知道为什么吗 ?

答案1

当我在 /etc/mongod.conf 中添加安全授权时,我解决了我的问题:

security:
    authorization: enabled

我不再收到警告。
